Sulfuration is bonded with the elastomer 18 of rubber system on the outer circumferential face of inner core 16, and elastomer 18 extends radially and be formed roughly X word shape respectively, with assembled state shown in Figure 1 this elastomer 18 is pressed in the rack tube portion 12.That is, the edge that is shaped as shown in Figure 1 of this elastomer 18 is the shape that the mutually orthogonal center line C1 in center, C2 direction are stretched out respectively with axle center S.
Specifically, a pair of pressure contact portion 26 stretches out respectively along the center line C1 in two center lines, and the end of this a pair of pressure contact portion 26 is crimped on the inner peripheral surface of rack tube portion 12.In addition, stretch out respectively along the center line C2 of elastomer 18 a pair of blocked part 28 that covers the backstop support 16A of inner core 16, and the inner peripheral surface with rack tube portion 12 is relative respectively to make the end of a pair of blocked part 28.
Make pressure contact portion 26 as shown in Figure 1 be shaped as long roughly rectangular along center line C1, be provided with in the end of this pressure contact portion 26 on the circumferencial direction width greater than base end part side width, towards the outstanding protuberance 26A in the circumferencial direction outside.Thus, can not make elastomer 18 along the spring constant of center line C1 greatly more than required, can guarantee as pressure contact portion 26 with the enough big area of the contacted area of contact of rack tube portion 12 inner peripheral surfaces.
And before being pressed into rack tube portion 12, the surface of contact that is used for contacting with rack tube portion 12 of pressure contact portion 26 is the convex curved surface that radius of curvature is slightly smaller than the radius of curvature of rack tube portion 12 inner peripheral surfaces.In addition, the axial length of the end of elastomer 18 equals the distance between end face 12A, the 12B of rack tube portion 12, elastomer 18 grow specific length along the natural length of center line C1 than the internal diameter of rack tube portion 12.By doing as described above, elastomer 18 is compressed with the difference along the internal diameter of the natural length of center line C1 and rack tube portion 12 of elastomer 18 along center line C1, and pressure contact portion 26 is to be crimped on the inner peripheral surface of rack tube portion 12 with the corresponding plus-pressure of this decrement.
As shown in Figure 1 to Figure 3, the radially inner side of rack tube portion 12, with the contacted part in end of a pair of pressure contact portion 26 of the vibration control equipment 10 of present embodiment on, be formed with prominent shape pars convoluta 34 respectively, prominent shape pars convoluta 34 is crossed over the whole width of rack tube portion 12 along axle center S direction, and it is outstanding to be L word shape with the height H more than or equal to rack tube portion 12 thicknesss of slab.
That is, add up to be provided with 4 prominent shape pars convolutas 34 on the inner peripheral surface of rack tube portion 12, a pair of prominent shape pars convoluta 34 in the middle of them disposes accordingly with side's pressure contact portion 26 of elastomer 18, and remaining a pair of prominent shape pars convoluta 34 disposes accordingly with the opposing party's pressure contact portion 26.This result is, under the state that elastomer 18 is pressed in the rack tube portion 12, a pair of prominent shape pars convoluta 34 contacts respectively with as the protuberance 26A along the two end part of the pressure contact portion 26 of rack tube portion 12 inner peripheral surfaces.
On the other hand, though the circumferencial direction width that makes blocked part 28 fully greater than the circumferencial direction width of pressure contact portion 26, the wall thickness of the part of stretching out along center line C2 of blocked part 28 is because the backstop support 16A of inner core 16 and thinner.With this, the natural length along center line C2 of elastomer 18 is lacked specific length than the internal diameter of rack tube portion 12.Thus, do not have the external force effect between inner core 16 and rack tube portion 12, under the reset condition of resiliently deformable, as shown in Figure 1, the inner peripheral surface of the end of blocked part 28 and rack tube portion 12 is not apart for elastomer 18.
And, though making the end face of this blocked part 28 is the convex curved surface of radius of curvature less than the radius of curvature of rack tube portion 12 inner peripheral surfaces, but as shown in Figure 3, on the end face of this blocked part 28, along the circumferential direction be provided with the projection 28A of the rib shape that extends vertically with constant space.
On vehicle body (omitting diagram), be fixed with backbone metal accessory 20 as the portion of being shaken, by sheet metals such as corrosion resistant plate is crooked as shown in Figure 3, and make this backbone metal accessory 20 structure rectangular with respect to base plate 30 for side plate 22,24 is bent to from the axial two end part of base plate 30.
Be formed with the through hole 30A that penetrates the thickness of slab direction respectively at the two end part of this base plate 30, on the upper surface of base plate 30, wait nut 33 to be fixed in a pair of through hole 30A top bulk by welding.Thereby to vehicle body fixed support Metal fittings 20 time, the bolt by will passing the lip part of being located at body side (omitting diagram) screws in the nut 33 from the underside side of backbone metal accessory 20, and to vehicle body fixed support Metal fittings 20.
The pair of side plates portion 22,24 of backbone metal accessory 20 vacate and end face 12A, the 12B of rack tube portion 12 between distance interval about equally, to be parallel to each other and identical mutually shape forms.In addition, about equally from the thickness of slab of the outstanding length of the outstanding positioning part 12C of end face 12A, the 12B of rack tube portion 12 and side plate 22,24.And,, be formed with respectively and corresponding shaped aperture portion of rack tube portion 12 32 at the central part of side plate 22 and the central part of side plate 24.
Promptly, this opening portion 32 is formed Fig. 1 to be the roughly U word shape of opening end 32A near shown in Figure 3, the upper end portion with side plate 22,24, opening portion 32, and the bottom of opening end 32A opposition side be formed with corresponding recess 32B with the positioning part 12C of rack tube portion 12.In addition, between the opening end 32A and recess 32B on the inner peripheral surface of opening portion 32, be formed with the curved face part 32C of radius of curvature than the concavity of the little specific length of radius of curvature of rack tube portion's 12 inner peripheral surfaces.
This recess 32B is recessed into roughly U word shape from the imaginary surface that curved face part 32C has been prolonged towards radial outside, and the bottom that makes recess 32B is the radius of curvature curved surface about equally of radius of curvature and rack tube portion 12 outer circumferential faces.But as shown in Figure 1, the bottom circumference of this recess 32B is longer than the girth of outer circumferential face of the positioning part 12C of rack tube portion 12 slightly.
At this, the straight line that the circumferencial direction central point of the opening end 32A of opening portion 32 is connected with the circumferencial direction central point of the bottom of recess 32B, base plate 30 with respect to backbone metal accessory 20 tilts with predetermined angular, with above-mentioned straight line is symmetry axis, and making opening portion 32 is with respect to the axisymmetric shape of this symmetry.In addition, in the vibration control equipment 10 of assembled state, as shown in Figure 1, elastomer 18 is fixed into the center line C2 that makes blocked part 28 and the symmetry axis of opening portion 32 coincides from axially seeing.
In addition, in the vehicle of the vibration control equipment 10 that is suitable for present embodiment, the major part load that is caused by the deadweight of motor is by not doing supporting such as illustrated other vibration control equipments.Thereby even under the installment state that motor is equipped on the vibration control equipment 10, when the vibration from motor was not delivered to vibration control equipment 10, rack tube portion 12 remained on the roughly coaxial mutually position with inner core 16.In addition, under identical installment state, when the vibration transfer from motor had arrived vibration control equipment 10, elastomer 18 was out of shape and makes rack tube portion 12 and inner core 16 produce relative displacements.
Next, the effect of the vibration control equipment 10 of present embodiment is described.
In the present embodiment, be fixed with elastomer 18 on the outer circumferential face of the inner core 16 that is formed tubular and is connected with motor, this elastomer 18 has a pair of pressure contact portion 26 of outstanding form respectively at outer circumferential side.And, by a pair of pressure contact portion 26 is contacted with interior all sides of rack tube portion 12 but not be pressed into this elastomer 18 bondingly, make this rack tube portion 12 by elastomer 18 supporting inner cores 16.
And, the radially inner side of rack tube portion 12 part, respectively with the contacted position, end of a pair of pressure contact portion 26 of elastomer 18 on, be provided with the whole width of the radially inner side part of crossing over rack tube portion 12, be the outstanding prominent shape pars convoluta 34 of L word shape with height more than or equal to rack tube portion 12 thicknesss of slab.In addition, this rack tube portion 12 is fixed on the backbone metal accessory 20, and this backbone metal accessory 20 is to be used for the structure that is connected with vehicle body.
Thereby, if from motor along the vibration transfer of the vibration input direction S1 of center line C2 to inner core 16, then follow elastomer 18 resiliently deformables, vibrational energy is absorbed by the internal friction of elastomer 18 and makes vibration attenuation, makes vibration be difficult to be delivered to the vehicle body that is connected with backbone metal accessory 20.At this moment, the internal friction of such elastomer 18 mainly absorbs vibrational energy by elastomer 18 along center line C1 resiliently deformable.In addition, along the excessive load of center line C2 direction from motor towards inner core 16 when transmitting, blocked part 28 connects with the inner peripheral surface of rack tube portion 12, thereby has limited the direction resiliently deformable of blocked part 28 along center line C2.
On the other hand, in the present embodiment, prominent shape pars convoluta 34 is crossed over whole width and is given prominence on the radially inner side part of rack tube portion 12.Therefore, the projection of using with the spline of the such prior art that forms by punch process such as drifts 122 is different, even rising height more than or equal to the thickness of slab of rack tube portion 12, also can easily be made this prominent shape pars convoluta 34 by bending.
In sum, according to the vibration control equipment 10 of present embodiment, can be easily with the height H of the shape pars convoluta 34 of dashing forward form necessary height, promptly more than or equal to the height of rack tube portion 12 thicknesss of slab.Therefore, even become big and be subjected to doing the time spent, also can improve the backstop function around the external force of the sense of rotation of axle center S at as shown in Figure 1 common vibration input direction S1 and the differential seat angle between the maximum input direction S2.This result is that the pressure contact portion 26 that elastomer 18 can not occur is crossed the prominent shape pars convoluta 34 of rack tube portion 12, and makes the phenomenon of this pressure contact portion 26 along interior all side shiftings of rack tube portion 12.
On the other hand, vibration control equipment 10 according to present embodiment, both ends of the surface 12A, the 12B of rack tube portion 12 in pair of side plates portion 22,24 clampings of backbone metal accessory 20, and the curved face part 32C of pair of side plates portion 22,24 extends from rack tube portion 12 inner peripheral surfaces towards axle center S side respectively and relative with the side of the pressure contact portion 26 of elastomer 18.
Thereby, even when the external force along axle center S acts on the elastomer 18 that is pressed in the rack tube portion 12, also can utilize side plate 22,24 restriction elastomers 18 courts to move axially, and elastomer 18 is not moved laterally from the axial end of rack tube portion 12.With this, elastomer 18 can not come off in rack tube portion 12.In addition, in the present embodiment,, therefore can more reliably elastomer 18 be pressed in the rack tube portion 12 because a pair of pressure contact portion 26 is present in respectively on the position of the core that clips elastomer 18.
